- Unsaturated polymers such as the natural and synthetic rubbers are often reinforced with fibers or textiles made from organic or inorganic fibers.
- reinforcing substrates include cords, fibers and textiles made of carbon, nylon, aramid, cotton, silk, rayon, wool, polyester, glass, steel and combinations of the same.
- the unsaturated polymers include, for example, polymers made from butadiene, styrene, isoprene, isobutylene, acrylonitrile, ethylene, propylene, chloroprene, and derivatives of the same.
- the applications for such reinforced polymers include tires, hoses, pressure vessels, and other such fiber-reinforced articles.
- adhesion promoter is a resorcinol-formaldehyde-latex (RFL) which has been widely used and modified since its invention by Charch. Its use was taught in U.S. Pat. No. 2,211,945. As the term RFL indicates, the resin is usually resorcinol-formaldehyde (RF) copolymer. However, other resins such as acrylic polymers, phenol polysulfides, phenol-formaldehyde type polymers may be used. Examples of these are taught in U.S. Pat. No. 4,472,463; Great Britain 2,147,303, and U.S. Pat. No. 4,448,813.
- the latex in the RFL system is usually butadiene/styrene/vinyl pyridine polymer This polymer has been the industry standard since it was invented by Mighton, U.S. Pat. No. 2,561,215.
- the RFL is applied as a coating to the substrate, which is subsequently heat-treated to cure (i.e., "crosslink") the RFL resin.
- the unsaturated elastomer from the latex remains uncured
- the matrix elastomer is then applied to the RFL-treated substrate and the composite is subsequently cured to form the product.
- the present invention provides a heretofore unknown latex composition which acts in a resin formulation as an adhesion promoter between organic substrates and unsaturated polymers
- the latex can be a dispersion of a copolymer of styrene and butadiene with an amine substituted alkyl acrylate; or it can be a dispersion of a shell/core polymer where the core is a styrene/butadiene copolymer and the shell comprises a copolymer of the styrene, butadiene, and the acrylate
- the composition is generally formed in an emulsion copolymerization.
- the composition is then used in a resin/latex formulation to form a coating of reinforcing substrates and thereby provide adhesion between the reinforcing substrate and an unsaturated polymer matrix.
- An adhesion promoter is provided which is the copolymerization product of styrene, butadiene and an amine substituted alkyl acrylate
- the amine substituted alkyl acrylate has the general Formula I ##STR2## wherein R 1 is hydrogen, or alkyl having 1 to 4 carbon atoms, and preferably R 1 is hydrogen or methyl, and most preferably R 1 is methyl; R 2 is an alkyl having from 1 to 8 carbon atoms, and preferably 2 to 4 carbon atoms; and R 3 and R 4 are the same or different and are hydrogen, aliphatic having 1 to 8 carbon atoms, or aromatic or aliphatic substituted aromatic having 6 to 8 carbon atoms or together with the nitrogen are heterocyclic having 3 to 8 carbon atoms, or oxygen, sulfur, and/or halogen derivatives of the same; and preferably R 3 and R 4 are hydrogen or aliphatic having 1 to 4 carbon atoms where one may be hydrogen but not both; and most preferably R 3 and R
- the styrene is present from about 0 to about 30 percent, preferably from about 15 to about 28 percent, and most preferably from about 20 to about 25 percent; while the butadiene is present from about 55 to about 97 percent, preferably from about 65 to about 80, and most preferably from about 69 to about 78 percent, based on the total weight of the monomers in the adhesion promoter.
- the amine substituted alkyl acrylate is present in an amount of about 1 to about 15, preferably from about 2 to about 12, and most preferably from about 3 to about 10 percent by weight based on the total weight of the monomers in the adhesion promoter.
- the polymer is produced as a latex by emulsion polymerization. It is used in a resin/latex formulation to form a substrate coating which acts as an adhesion promoter which yields excellent adhesion as measured by ASTM test D-2138.
- the adhesion promoter can be used with various substrates and elastomers.
- the invention relates to a latex polymer which acts in a resin formulation between an unsaturated polymer matrix and a reinforcing substrate.
- polymer is used broadly herein to mean either a copolymer or an overpolymer or a shell/core polymer. This polymer is made from 0 to 30 percent, and preferably 15 to 28 percent, and most preferably 20 to 25 percent styrene; 55 to 97 percent, and preferably 65 to 80 percent, and most preferably 69 to 78 percent butadiene; and 1 to 15 percent, and preferably 2 to 12 percent, and most preferably 3 to 10 percent by weight of an amine substituted alkyl acrylate, all percentages, based on the total weight of the monomers.

- the amine substituted alkyl acrylate has a general formula I ##STR3## wherein R 1 is hydrogen, or alkyl having 1 to 4 carbon atoms, and preferably R 1 is hydrogen or methyl, and most preferably R 1 is methyl; R 2 is an alkyl having from 1 to 8 carbon atoms, and preferably 2 to 4 carbon atoms, and R 3 and R 4 are the same or different and are hydrogen, aliphatic having 1 to 8 carbon atoms, or aromatic or aliphatic substituted aromatic having 6 to 8 carbon atoms, or together with the nitrogen are heterocyclic having 3 to 8 carbon atoms, or oxygen sulfur, and/or halogen derivatives of the same; and preferably R 3 and R 4 are hydrogen or aliphatic having 1 to 4 carbon atoms where one may be hydrogen but not both; and most preferably R 3 and R 4 are both ethyl, or R 3 is butyl and R 4 is hydrogen.
- Methacrylate amino esters are preferred over acrylate amino esters, because they exhibit more favorable, higher combining ratios during copolymerization. Increasing the number of carbon atoms in the groups attached to the nitrogen atom of the acrylic esters serves to decrease the rate of hydrolysis of the ester, especially in alkaline media. This is believed to be an advantage in the invention as practiced.
- Specific examples of preferred acrylates include diethyl amino ethyl methacrylate, and monobutyl amino ethyl methacrylate.
- the polymers are latex polymers produced by emulsion polymerization. When the random copolymer is produced, all monomers are charged at the same time to the reactor.

- suitable resins include acrylic polymers, phenol polysulfide polymers and copolymers from formaldehyde and hydroxy benzenes such as xylenols and cresols.
- the dry solids ratio of latex polymer to resorcinol-formaldehyde is from about 1 to about 10, and preferably from about 1 to about 7, and most preferably from about 2 to about 5.
- the most preferable latex/resin ratio may vary depending on the reinforcing substrate, the resin, and the unsaturated polymer matrix to which it must be adhered.
- the reinforcing substrate is dipped into the resin/latex adhesive and the excess is removed.
- the coated substrate is dried, and then cured at 150° C. to about 250° C., and preferably from about 175° to about 230° C. for 30 seconds to 10 minutes, depending on the temperature, and preferably from about 1 to about 4 minutes.
- the treated substrate is then embedded into the unsaturated polymer which already contains curing agents, etc.
- This composite is then cured under pressure at a temperature of from about 100° to about 200° C., and preferably from about 130° to about 180° C. for 10 to about 30 minutes, depending on the temperature, and the thickness of the composite.
- Suitable substrates include cords, fibers and textiles made of cotton, rayon, silk, wool, polyester such as poly(ethylene terephthalate), aliphatic and aromatic polyamides such as Nylon 66 and poly(phenylene terephthalamide), carbon, glass and steel.
- polyester such as poly(ethylene terephthalate), aliphatic and aromatic polyamides such as Nylon 66 and poly(phenylene terephthalamide), carbon, glass and steel.
- some of the reinforcing substrates give best results if pretreated, before coating with the resin-latex composition of this invention, e.g., poly(ethylene terephthalate) "polyester”, i.e., fibers treated with a polyisocyanate as taught in U.S. Pat.

- the resin latex formulation promotes adhesion between the substrate and an unsaturated polymer matrix.
- unsaturated polymer in this instance it is meant a polymer having unsaturation in the backbone or pendant groups and not aromaticity. This is most generally olefinic unsaturation. It is believed that the adhesion promoter of the present invention is broadly applicable for use with all sorts of polymers having olefinic unsaturation.
- Examples of specifically preferred unsaturated polymers include styrene/butadiene, natural rubber or polyisoprene, polychloroprene, butadiene/isobutylene copolymer, and ethylene/propylene/butadiene terpolymers
- the adhesion promoter of the present invention results in excellent adhesion as measured by ASTM Test D-2138.
- adhesive failure can occur at two interfaces between the substrate and the RFL, and between the RFL and the elastomeric matrix.
- cohesive failure may occur in the substrate, the RFL or the elastomeric matrix.
- interfacial bond strengths as well as the cohesive strength of the RFL are greater than the cohesive strengths of either the substrate or the elastomeric matrix.
- failure in the ASTM D-2138 test occurred primarily within the elastomeric matrix. This means that adhesion between the elastomer matrix and the RFL, adhesion between the textile substrate and the RFL, and the cohesive strength of the RFL are all greater than the measured and reported adhesion value.
- a random terpolymer of butadiene, styrene, and diethylaminoethylmethacrylate (DEAM) was prepared using the recipe in Table I.
- Aqueous stock solutions were prepared with one or more of the following ingredients: potassium oleate, potassium hydroxide, trisodium phosphate, sodium bicarbonate, sodium hydrosulfite, and sodium persulfate. All stock solutions and the water were purged with dry nitrogen gas before use.
- SBR-VP butadiene-styrene-vinylpyridine latex was prepared using the recipe in Table I, except that 2-vinylpyridine (VP) was substituted for DEAM.
- Part B was then prepared The addition of natural rubber latex to the formulation is not necessary for RFLs prepared from SBR-DEAM to act as effective adhesion promoters. Part A was then added to Part B and was well mixed.
- Part C was prepared and was added to the mixture of Parts A and B. The RFL was then used within 24 hours.
- RFL-A was prepared using the formulation in Table II.
- RFL-B was prepared in a similar way to RFL-A but without the acrylic or the natural rubber latices.
- Nylon 6,6 (840/2 denier) tire cords were dipped into a bath containing the RFL-A mixture, the excess RFL was removed, and the cords were dried for 2 minutes at 150° C. The dried cords were then baked for 1 minute at 220° C.
- PET (1000/2 denier) cords were first dipped into the EI mixture, the excess mixture was removed, and the cords were dried for 2 minutes at 150° C. The dried cords were then baked for 1 minute at 240° C. They were then treated with the RFL mixture as outlined above.
- the following unsaturated polymer matrices were used for the preparation of H-adhesion test samples. These polymer compounds are typical of those used in tires and other industrial rubber products.
- H-adhesion test samples were prepared and tested according to ASTM D-2138. The results obtained are shown in Table IV.
- SBR-DEAM latex in an RFL formulation, provides excellent adhesion between typical tire reinforcement materials and unsaturated polymer compounds.
- the level of adhesion is comparable to that obtained with the SBR-VP latex that is typically used today.
- a terpolymer of butadiene, styrene, and diethylaminoethylmethacrylate (DEAM) was prepared using the recipe in Table V.
- This recipe is similar to that in Table I except that potassium oleate has been replaced by Surfactant A.
- Surfactant A is an ammonium salt of sulfated nonylphenoxy poly(ethyleneoxy) ethanol.
- This formulation uses an additional surfactant--Surfactant B, which is ammoniumlauryl sarcosinate.
- RFL RFL (RFL-C) was prepared using a formulation similar to that in Table II in Example 1, the only difference being that the only latex used was either SBRDEAM or SBR-VP.
- SBRDEAM SBR-P
- the amount of natural rubber solids in the formulation shown in Table II in Example 1 was replaced with either SBR-DEAM solids or SBR-VP solids, depending on which latex was being used in the formulation.
- SBR-VP used in this experiment was manufactured by The BFGoodrich Company and is sold under the brand name Goodrite 2528x10.
- a core-shell SBR-DEAM latex was prepared using the formulation in Table V.
- the core-shell structure was created by initially introducing only 2.5 parts of DEAM into the reactor. The rest (7.5 parts) was added at about 70 percent conversion.
- the core and the shell are composed of SBR-DEAM polymer; the concentration of DEAM in the shell is much greater than that in the core.
- a core-shell SBR-DEAM latex was prepared using a formulation similar to that in Table V; the only exceptions were that the levels of butadiene and DEAM were 72.0 and 3.69 parts respectively.
- the core-shell structure was created by introducing all of the DEAM into the reactor at 49 percent conversion.
- the resulting latex particles are expected to contain a core of SBR polymer which is covered with a shell of SBR-DEAM polymer.
- Preparation of the RFL, treatment of 1600/2 PET tire cord, adhesion sample preparation and testing were all the same as in Example 2. The adhesion results obtained are shown in Table VIII.
